The weld says "Thank you PCTI".

For those who missed my previous posts, I am redoing my welder using a
modern three phase firing system by PCTI. My hope is that this
controller would allow me to do constant current and constant voltage
welding (stick/TIG and MIG), as well as plasma cutting if I rewire my
transformer for higher voltage. (this rewiring would be done
dynamically by contactors)

Some pictures of the rectifier and controller are he

Many thanks go to Glen from s.e.d., who gave me great advice
throughout.

You are running beads. That is very good, very good indeed.

Friendly suggestion: don't sign up for any competitions just yet.....
but by all means keep on truckin', make more beads.

Thanks... I know that I am not good at welding... Although stick
welding is very forgiving...

But I am happy that this controller is working, that means that I
could potentially go ahead with making it into a more usable welder. I
am not sure if I mentioned it, but this transformer can be
reconfigured for OCV of 300 volts and thus plasma cutting.

I got some noname plasma torch and will soon work on this. My plan is
to use contactors to change it from a 200A, 90V OCV welder, to a 300V
OCV plasma cutting power supply, by flipping a switch and engaging
different contactors. I may be able to do it over the weekend.
